Some On Cloud styles run half a size small; sizing up half a size is often the right call. Some styles have a slightly wider toe box, while others run more narrow. If your feet are wide, almost always go up a half size.

If a wearer frequently falls between half sizes, going with the half-size up is the better bet.

Socks do take up room so If you need extra width room, sizing up half a size can help — but over-compensating risks heel slippage.

Most On shoes perform very well for narrow to medium feet. The Cloudmonster 2 tends to feel the most performance-secure, while the Cloudrunner offers a wider fit and may be more comfortable for those with wide feet.

ON shoes can be ordered in half sizes, ranging from women's 5–11 and men's 7–14.

On offers limited wide options compared to some brands. We find that we can fit about 80% of our customers with the medium width and a selection of styles to choose from.

On's clean Swiss-design aesthetic with neutral tones drives heavy color-search volume, particularly among lifestyle buyers who want understated looks. Lt-grey, Beige, and soft pastels are key colors in the collection.

While HOKA's maximalist midsole reads as fashion-forward and New Balance dominates retro-runner aesthetics, On has carved its own lane in the performance-lifestyle crossover with a distinctly minimal, technical silhouette. HOKA tends to be a bit bulky, while New Balance are more fashion forward. ON's are styled in the middle of these brands with exceptional bounce.

On Cloud shoes are worth it for runners who want a shoe blending comfort, performance, and everyday versatility. They are useful beyond running — for everyday wear and walking — which increases their total value proposition.

For daily walkers and heavy users, replacement roughly twice per year is the expectation. Signs of wear include a flattened midsole feel, increased foot fatigue, knee or hip soreness returning, visible outsole wear, and heel slippage. Rotating your athletic footwear can extend the life of your footwear.

Long-term durability of On Cloud models is tied to many factors: frequent use, weight, rotation of footwear, indoor vs outdoor wear, and even misuse of function can affect the wear to any style.

Lab testing confirms On's CloudTec and Speedboard combination delivers a fun and energetic ride with high energy return of 59.4%, producing smooth and effortless transitions. This energy return pushes you into the next step, which helps you move forward with less effort.

ON offers a one-year warranty covering manufacturing defects, but normal outsole wear, midsole compression, cushion breakdown from heavy use, and cosmetic scuffs are not covered. Shoes worn out after 6–12 months of daily walking are considered normal use.

The exposed CloudTec pods often raise questions about water and debris entry into a shoe. But the outsole is sealed, and water doesn't typically enter that way. Water can enter through the fabric upper, and drying the shoe (no heat) is needed to maintain its integrity. Some On Cloud shoes are waterproof with a 3M membrane keeping water out of the inside of the shoe and protecting the foot from water entry.
